LLMs don’t crawl the web on demand. They build recommendations from training data plus, increasingly, real-time web search. The brands that appear are the ones with: (1) a clear category positioning that’s repeated across many third-party sites, (2) reviews and citations that the model has seen, and (3) for live-search models like Perplexity, recent press or content the model can fetch.
It’s not magic. It’s a downstream effect of what people are saying about you, where, and how often. The first job is to know whether you’re named at all — and the second is to know which prompts you’re winning vs losing.
